AI device identifies objects at the speed of lightElectrical and computer engineers have created a physical artificial neural network -- a device modeled on how the human brain works -- that can analyze large volumes of data and identify objects at the actual speed of light.

pH imbalance in brain cells may contribute to Alzheimer's diseaseScientists say they have found new evidence in lab-grown mouse brain cells, called astrocytes, that one root of Alzheimer's disease may be a simple imbalance in acid-alkaline -- or pH -- chemistry inside endosomes, the nutrient and chemical cargo shuttles in cells.

Mapping of magnetic particles in the human brain Researchers have for the first time mapped the distribution of magnetic particles in the human brain. The study reveals that the particles are primarily located in the cerebellum and the brainstem, which are the more ancient parts of the brain.
